bug#16088: 24.3; ERC buffer name

[Cédric Chépied]

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':


Hello,

I don't know if this is really a bug. Please close it if you don't want to fix
it.

I'm using ZNC as irc bouncer to connect to several networks. For ERC, I'm
connected to the same server several times with different erc-email-userid.

If I talk with somebody called "sb" on freenode and with another person also
called "sb" on oftc, ERC only opens 1 buffer called "sb" and I receive all
messages in the same buffer. When I write in this buffer only 1 "sb" receive
something.


I made this ugly fix cause I don't know erc code at all:

(defun erc-get-buffer-create (server port target &optional proc)
  "Create a new buffer based on the arguments."
  (setq target (concat target "@" (prin1-to-string (erc-current-network))))
  (get-buffer-create (erc-generate-new-buffer-name server port target proc)))

All buffers are now named channel@server and I got sb@freenode and sb@oftc.

Regards,
